Stadig færre er bosatt på det stedet de vokste opp. Likevel kan slike steder være viktige for folks identitet og deres integrering i ulike fellesskap. En slik tilknytning kan analyseres som en form for slekting, der individer gjennom relasjoner og praksiser vedlikeholder og knyttes til fellesskap som for eksempel det kvenske. Materielt sett tar slike prosesser ofte utgangspunkt i en allmenn forståelse ...

Microalgae are the main source of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential for the healthy development of most marine and terrestrial fauna including humans. Inverse correlations of algal EPA and DHA proportions (% of total fatty acids) with temperature have led to suggestions of a warming-induced decline in the global production of these biomolecules ...

As an engineering field, the goal of synthetic biology is to design, build and implement technological solutions that advance human capability. To achieve this, synthetic biologists must be open to exploring new avenues of engineering strategies and move beyond tradition. The host-chassis has historically been an overlooked design variable in the field of synthetic biology. We show in this thesis ...

Quantifying the biomass, or number of individuals, diversity, and distribution of marine species is a critical aspect of understanding and managing marine ecosystems. In recent years, there has been growing interest in using environmental DNA (eDNA) for marine ecosystem management and biodiversity assessment. However, the main challenge hindering eDNA applicability has been the inability to infer ...

A considerable number of antibacterial agents are derived from bacterial metabolites. Similarly, numerous known compounds that impede bacterial virulence stem from bacterial metabolites. Enteropathogenic Escherichia coli (EPEC) is a notable human pathogen causing intestinal infections, particularly affecting infant mortality in developing regions. These infections are characterized by microvilli ...

Diving mammals are perpetually required to manage low-oxygen conditions throughout their lives. The mammalian brain is an organ particularly vulnerable to low oxygen levels due to its high energy demands, which require steady aerobic ATP production. The brain of the deep- diving hooded seal (Cystophora cristata) demonstrates remarkable tolerance to hypoxia. Studies suggest that this brain hypoxia ...

Pots are traditional fishing gear type largely employed in Mediterranean Small Scale Fisheries (SSFs). Their often higher species selectivity and catch quality compared to other gear types such as passive set nets or trawls are appealing characteristics for reducing the impact on benthic communities and diversifying fishing effort in the region. Despite this, in some SSFs, pots are still rarely used ...

Benthic (seafloor) remineralization of organic material determines the fate of carbon in the ocean and its sequestration. Bottom water temperature and labile carbon supply to the seafloor are expected to increase in a warming Arctic and correspondingly, benthic remineralization rates. We provide some of the first experimental data on the response of sediment oxygen demand (SOD), an established proxy ...

Introduction: Groundwater demand has been considerably heightened due to rapid urban growth, specifically in arid areas that rely primarily on groundwater. This study aims to utilize remote sensing and aeromagnetic data, combined with the Analytic Hierarchy Process (AHP) based GIS, to evaluate potential groundwater zones in the Sohag area, Egypt.<p> <p>Methods: Nine thematic layers, including ...

Salmonid aquaculture, a major component of the Northern European, North American, and Chilean coastal economies, is under threat from challenges to gill health, many of which originate from plankton communities. A first step toward mitigating losses is to characterize the biological drivers of poor gill health. Numerous planktonic taxa have been implicated, including toxic and siliceous microalgae, ...
